Abstract
A rolling rotor motor/compressor has a stator/cylinder with an internal rotor/piston. The stator/cylinder and rotor/piston together define a chamber and a vane extends into this chamber when the device is compressor. The rotor/piston has a pair of axially extending shafts and a pair of counterweights coact with the shafts for balancing while permitting radial movement of the rotor/piston within the stator/cylinder. This permits unloading of the compressor such as when there is a liquid slug.
Claims6
A rolling rotor motor means comprising:
- housing means;
- stator means within said housing means and having a plurality of windings and a cylindrical opening therein;
- said housing means having a pair of shafts axially spaced from said cylindrical opening and coaxial therewith;
- cylindrical rotor means located within said cylindrical opening and defining therewith a chamber;
- said rotor means having a pair of axially extending shafts;
- a pair of counterweight means each coacting with one of said pair of shafts of said housing means and a corresponding one of said pair of shafts of said rotor means whereby said pair of counterweight means and said rotor means move as a unit responsive to the sequential actuation of said plurality of windings.
